12TW3 Subwoofer Driver

Congratulations on your purchase of a JL Audio subwoofer component. Your JL Audio subwoofer

is a precision loudspeaker which has been engineered to produce the highest quality sub-bass

performance in your vehicle. Authorized JL Audio dealers have extensive technical information

for many different applications of your new speaker. They also have the knowledge, skills and tools

to build a high-quality enclosure that will maximize the performance of your speaker. We highly

recommend that you have your enclosure built by an authorized JL Audio dealer.

Inside you will find specifications and two recommended enclosures for your speaker; one is a

sealed enclosure, the other is a ported design. Both types of enclosures will give you excellent sound

quality and low-frequency extension. The sealed enclosure is a better choice if space is extremely

tight, but the ported enclosure will produce 3dB more output at the same power if you have the

extra space to work with.

JL AUDIO 12TW3-D4 / 12TW3-D8 12TW3 Dual Voice Coil Wiring

Please Note: The TW3 is a dual voice coil driver.

BOTH voice coils must be connected to the amplifier

(in series or parallel) for the speaker to operate

properly. To accomplish this, each TW3 features a pair

of main input connection push-terminals for each

voice coil. Verify that the connections are properly

configured based on these wiring diagrams to

achieve the desired load prior to sending signal to

the subwoofer.

All specifications are subject to change without notice.

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.

** Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to

other subwoofers to determine which one is “louder” !

*** Re (DC resistance) is measured with the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications

remain the same.
